WEIGHT-VERIFIER.

SPECIFICATION forming part of Letters Patent No. 783,993, dated February 28, 1905.

Application filed May F1903. Serial No. 155,693.

To (L//// w/tont it TIMI/y con/earn:

Be it known that I, AUGUS'PE A. GAILLE, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in VVeight-Veriliers, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to coin controlled weighing-machines of that type in which the operator may first register his estimate of the weight and then ascertain the actual weight by the operation of the mechanism controlled by the coin. If the registered weight and actual weight correspond, the coin operating the mechanism is returned, but otherwise the coin is retained in the machine.

It is the object of the present invention to obtain greater accuracy and certainty in operation of the mechanism than in constructions heretofore employed.

To this end the invention consists in thepeculiar construction, arrangement, and combination of parts, as hereinafter set forth.

In the drawings, Figure 1 is a perspective view of the machine. Fig. 2 is a front elevation of the upper part of the machine with the casing broken away to show the operating mechanism. Fig. 3 is a rear elevation of the parts shown in Fig. 2. Fig. 4 is a vertical section through the casing, showing in side elevation the mechanism illustrated in Figs. 2 and 3. Fig. 5 is a similar view, drawn on a larger scale and showing some of the parts in different position, showing locking connection for the return of the coin. Fig. 6 is a horizontal section on line X X, Fig. 5. Fig. 7 is a horizontal section on line Y Y, Fig. 4. Fig. 8 is a perspective view of the locking mechanism for the stop-arm. Fig. 9 is an enlarged elevation of a portion of Fig. 3, illustrating the actuating and controlling means for the-locking mechanism. Figs. 10, 11, and 12 are enlarged elevations of portions of Fig. 3, illustrating the coin-controller in various positions in its operation.

In general construction the machine comprises a weighing-platform A and an upright column or standard B, supporting an enlarged casing (J. This casing has on its front face the dial or indicator I), covered by the transparent panel E. Upon the dial .D both the estimated and actual weight are indicated, but by separate index-hands, respectively. F and G. The index or set arm F is normally under the control of the operator and may be set at any desired point upon the dial I). .The index G is normally locked from operation and can only be released by the insertion of a coin in the machine. \Vhen once released, it is beyond the control of the operator and assumes a position which indicates the actual weight. At the same time the operator loses control of the index F, so that its position may not be shifted until after the weight is removed from the platform. Thus the diliierence between the estimated and the actual weight will be apparent to the observer.

To accomplish the result above set forth, the

index F is provided with an external operating-handle H and an internal connection I, which normally couples it with the index F. In the construction shown the index F is secured to a stub-axle journaled in the casing, to which is also secured an arm lrI', having a handle Hat its outer end. The handle H projects through a segmental slot in the front face of the casing. The connection I consists of an arm a, secured to the stub-axle, and a lever Z), pivoted to said arm and having a latchpin 0. This pin is adapted to engage with a keeper (Z on the index-arm F, being pressed therein by an operating-spring With this construction the index F will move by the actuation of the handle H whenever the pin 0 is in engagement with the keeper (Z, and when out of engagement, but free to be actuated by the spring 0, it will automatically engage with the keeper when moved in registration therewith.

The index G is secured to an arm J, which is pivoted upon the pin J within the casingC and preferably in axial alinement with the pivot of the index F.

K is a torsional spring sleeved upon the pin J and connected at one end to the arm J and at its opposite end to a fixed portion of the frame I, which supports the said pin. Under the actuation of this spring the arm J will be movement is prevented by a lock M, which safe.

holds said arm with the index at the zero-poin t.

The arm J performs a number of different functions, which will behereinafter described; but its primary function is to actuate the index (1- in the manner just described. In order that it may indicate the actual weight, it is adapted to cooperate with a movable member actuated by the weighing mechanism and which arrests the arm J in a position corresponding therewith, which accurately indicates the weight upon the platform. This member, actuated by the weighing mechanism, I shall term the stop-arm and, as shown, it is formed by an arm N, secured to the pivot O in axial alinement with the pin J. Upon this pivot O is a pinion O, which meshes with a vertically-movable rack P. P is secured to a member Q, which is connected with the steelyard-rod Q, extending down through the column B and having suitable connection (not shown) with the weighing-platform. The member Q is also connected with the weighing-springs R, which, as shown, are anchored to a stationary member R, forming a portion of the frame. With the construction just described the weight of the platform A will actuate the steelyard-rod Q and member Q, until balanced by the springs B. This movement will be imparted to the rack P, which will rotate the pinion O and arm N, so as to swing the latter in a position determined by the weight on the platform. The stop-arm N is concealed from view of the operator; but whenever the arm J is unlocked and swung by the actuation of the spring K it will be arrested by engaging with the stoparm N, so as to indicate on the dial the position of said arm and also the weight upon the platform.

As has been described, the machine is designed to liberate the indicator G upon the insertion of the coin, and when this indicator assumes a position corresponding to the position of the index F, previously positioned, the coin will be returned. To secure accurate and certain operation of the mechanism to effect this result, it is necessary that the stoparm N should be positively locked in position before it arrests the movement of the arm J. It is further necessary that the index F should be uncoupled from its actuating handle H, so as to be beyond the control of the operator, and thus prevent him from subsequently moving it into registration with the index G. It is further necessary that the coin used to liberate the arm J should be controlled during the swinging of said arm and that when said arm is arrested in the position in registration with the index F the coin should be liberated and directed into a chute leading out from the case. Finally, it is necessary that after the operation and the removal of the weight from the plat- The rack form the parts should be restored to their normal position and that the coin when retained within the casing should be deposited in the The mechanism for obtaining these various results is of the following construction: The coin is inserted through a slot in the easing into a chute S, which extends downward within the casing and is in alinement with the returnclmte T. 7" is a trip-arm constituting a portion of the lock M for holding the arm J in its normal position. This trip-arm is pivotally connected to the arm J and extends into the chute S in the path of the coin passing therethrough. It is also provided with the lockingshoulder f, which engages with the keeper f, the arrangement being such that the coin in traveling through the chute S will trip the arm 7", disengaging the shoulder f from the keeper f and permitting the arm J to swing under the actuation of the spring K. Intermediate the ends of the chute S and the chute T is arranged a'coin-controller U. This consists of a defiectory plate q, which in normal position is arranged to deflect the coin after leaving the chute S and to direct it into a chute V, leading to the safe V. The plate r is secured to a rock-arm pivotally secured to the frame. g is a spring connected to said rock-arm, tending to draw the plate y from its normal position. /t is a lug or arm projecting from arm J into the path of arm g, extending from the plate r These arms a and g cooperate to hold the plate r/ in its normal position against the actuation of the spring g. As soon, however, as the arm J is released the arm /1. will be withdrawn, which will permit the arm to swing, shifting the plate 0 and interposiug a stop in the path of the coin. This stop will temporarily hold the coin in the chute S. Further movement of the arm r is prevented by the contacting of an arm on the plate 5 with a stop 1', as shown in Fig. 11. The locking of the stoparm N is also effected by the swinging of the arm J by the following mechanism: j is a bearing upon the frame contacting with the rack-bar P. Z: is a locking-cam pivotally secured to the frame opposite the bearing j, but normally in a position to permit free movement of the rack-bar P. Za is a rock-arm connected with the cam in, the free end of which bears upon a stop 7t, carried by the member A, is an arm also connected to the cam Z' and extending upward therefrom, being provided at its upper end with a pivotal member Zr", which normally contacts with the stop X, which projects from the arm J and is actuated by the same. Z? is a spring connected with a laterally-extending arm F on the arm Z' and tending to rock said arm and the cam l in a direction to lock the rack P against the hearing j. The arrangement of parts is such that whenever the arm J is released the stop F, which is connected to the same, will be withdrawn, permitting the swinging of the arm A mitted.

and effecting the locking of the rack-bar P. This locking of the rack-bar will hold the stoparm N stationary through the medium of the pinion O. Thus when the arm J comes into engagement with the stop-arm N the latter is rigidly locked from movement. As shown, the engagement of the arm J with the stoparm N is effected by a hooked finger J on the arm J engaging with the eye N on the arm N, as shown in Figs. 4, 5, and 6. The throwing out of the coin is effected by the with- 'drawal of the stop a, which is automatically operated when the index-arms F and G are in registration by the following mechanism: 2; is a lever carrying the stop 6, which lever is fulcrumed atl upon the frame. "1? is a spring acting upon said lever to normally hold it against a stop 6 in which position the stop if is in the path of the arm m is a rockshaft pivoted in bearings upon the arm J and extending longitudinally thereof. in is a rockarm upon the rock-shaft m, which extends in oximity to a segment if, constituting a porn of the lever '21. 0 is an arm secured to ie upper end of the rock-shaft m, which is normally held in the position shown by dotted lines in Fig. 6 by the tension of a spring 112, connected to the rock-arm m. The arm 0 is preferably of the T-shape form shown in Fig. 5 and is pivoted at its lower end by the pin 0' to a block (ii-secured to the shaft m. At its upper end it is provided with a segmental slot which the pin 0 on block 0 engages, the construction being such that a limited rocking movement of 0 in a vertical plane is per- 0" is a spring for holding the arm 0 in its normal position. 1) is a stop upon. the arm N, which extends in proximity to the path of an arm 0 during the travel of the arm J. The arm (1' will not, however, engage with the stop p when in its normal position, (shown in dotted lines inFig. 6,) but must first be thrown into a position for engagement by the rocking of the shaft m, which carries the arm 0 into the position shown in full lines in Fig. 6 and also the rocking of said arm on the pivot 1/. Such a rocking of the arm 0 is effected whenever the arm J passes the indexarm F by the engagement of said arm 0 with a projecting finger q. The latter is pivotally secured to the arm F and is held normally in a position to project therefrom by the spring (7. Thus whenever the arm J is released and travels past the arm F the finger q will engage with the arm 0 and rock the same horizontally and vertically into position shown in full lines in Fig. 6, whereby the free end of said arm projects into the path of the stopp. If the stop-arm N is not in registration with the arm F, the finger q and arm 0 will disengage, and the latter can assume its normal position. (Shown in dotted lines, Fig. 6.) If, on the contrary, the stop-arm N is in registration with the arm F, the arm 0 will be projected into the path of the stop 7). This will cause the rocking of the arm 0 in the opposite direction, which through the medium of the rock-shaft m Will rock the arm m, which in turn will bear against the segmental portion 2 of the lever rocking said lever until the stop 6 is withdrawn from the path of the arm As soon as this occurs the stop y" will be withdrawn from the path of the coin, permitting the latter to drop from the coinchute S and into the return-chute T, which will carry it outside of the case.

It has been previously stated that the handle H is uncoupled from the stop-arm F during the operation of the mechanism controlled by the coin. This unlocking is effected by lever 1*, which is pivoted to the frame and extends horizontally in proximity to one arm of the lever 7). Another arm, a", of the lever w extends in proximity to a linger s on the arm Z. The arrangement is such that whenever the arm J is released by the disengagement of the lock M the fingers s will strike against the arm w of the lever 1, locking said arm and lever until the latter bears against the lever 7) and disengages the pin 0 from the keeper (Z. As a result the handle H is disconnected from the index-arm F and remains disengaged until the parts are restored to normal positions.

Afterthe operation of themachine and upon the removal of the weight from the platform the parts of the mechanism will be automatically returned to normal positions. This is accomplished first by the return of the platform and its actuating connections by the springs B. This movement cannot, however, immediately return the arm N, as the rack P is still locked by the engagement therewith of the'cam k. I

To provide for the independent returning of the weighing mechanism, a yielding connection is arranged between the member Q, and the rack-bar P. This is formed by slotting the raek-bar at t to slidingl y engage with the pin 6 on the member Q.

a is a spring for yieldingly holding the rackbar in a position where the pin 6' is at the lower end of the slot 6. The tension of this spring is sufficient to normally move the rack l with the member Q; but whenever the rack-bar is locked in fixed position by engagement of the locking-cam l; the spring in will yield and permit of an independent movement of the member Q.

The unlocking of the rack-bar P is effected during the independent return movement of the weighing mechanism and the member Q, through the following mechanism. As has been previously described, the cam Z has a rock-arm K secured thereto, the free end of which bears against a stop Z3, carried by the member Q. This stop A? will be withdrawn in the downward movement of the steelyardrod Q and member Q whenever a weight is upon the platform; but the cam will remain in unlocked position until after the withdrawal of the stop Z1 which is a part of the arm J and is actuated by the movement thereof. .In the return movement of parts the rack-bar P remains in locked position until the stop Z! on the member Q contacts with the rock-arm 7c and actuates said arm to release the cam k. The spring a will then actuate the rack-bar P to take up the lost motion occasioned by the sliding of the pin t in the slot 2., and this movement of the rack-bar will rotate the pinion O, returning the stop-arm N and carrying with it the arm J. The parts will thus be returned to normal position, and the lock M reengaging will hold the arm J in this posi tion until released in the subsequent operation of the machine.

The parts being constructed and the various mechanisms operating in the manner described the complete operation of the machine is as follows: The user desiring to verify a weight places the same upon a platform, which causes the actuation of the concealed stop-arm N, but does not indicate what the weight is. The estimated Weight may then be registered by a movement of the handle H until the index F is set at the desired point on the dial. The operator then inserts the coin in the chute S, which trips the latch-arm f of the lock M, releasing the arm J and permitting it to travel around the dial until arrested by the arm N. If the two index-arms are in coincidence, the coin-controller will be operated, through the mechanism previously deseribed,to release the coin from the chute S and permit it to travel into the return-chute T, which will carry it out from the case. If the index-arms are not in correspondence, the coin will still be retained in the chute S by the stop and will remain in this position until the weight is removed from the platform and the mechanism is restored to normal position. Upon the insertion of a coin and the releasing of the arm J the mechanism previously described will be operated to uncouple the index from its actuating-handle, so that the two index-arms will remain in their respective positions and be beyond the control of the operator until the weight is removed from the platform. \Vhenever the estimated and registered weights do not correspond, upon the removal of the weight from the platform and the return of the arm J the controller U will be restored to its normal position, in which it will deflect the coin from the chute S into the chute V, from which the coin will be deposited in the safe V.
